muscle activity• Desmin• Vimentin• Muscle actin• Alpha-smooth muscle actin

Diagnostic ModalitiesDiagnostic Modalities• Imaging modalities 5
– Echocardiography– CT– MRI– PET– PET/CT
• First reported use of PET/CT that assisted in the diagnosis of leiomyosarcoma of the inferior vena cava
5 Hemant D, et al. Australas Radiol. 2001 Nov;45(4):448-51.
![Page 18: ACP Case Presentation: LEIOMYOSARCOMA OF THE INFERIOR VENA ...](https://reader035.fdocuments.net/reader035/viewer/2022062703/5550eb20b4c905417d8b4f47/html5/thumbnails/18.jpg)
ManagementManagement• Not adequately described 8
– Limited international experience
– “Optimal management unknown”
8 Hines OJ, et al. Cancer. 1999 Mar 1;85(5):1077-83.
![Page 19: ACP Case Presentation: LEIOMYOSARCOMA OF THE INFERIOR VENA ...](https://reader035.fdocuments.net/reader035/viewer/2022062703/5550eb20b4c905417d8b4f47/html5/thumbnails/19.jpg)
ManagementManagement• Aggressive surgical treatment is
recommended 4
– Slow growth pattern – Relatively low metastatic potential– Complete resection 9
• feasible • associated with improved survival
• Chemotherapy and radiation therapy may serve as adjuncts 8

PrognosisPrognosis• Case series from Memorial
Sloan-Kettering 9
– 25 patients– Complete resection
•3-year survival rate - 76%•5-year survival rate - 33%
– Incomplete resection - No 3-year survivors
9 Hollenbeck ST, et al. J Am Coll Surg. 2003 Oct;197(4):575-9.
![Page 21: ACP Case Presentation: LEIOMYOSARCOMA OF THE INFERIOR VENA ...](https://reader035.fdocuments.net/reader035/viewer/2022062703/5550eb20b4c905417d8b4f47/html5/thumbnails/21.jpg)
PrognosisPrognosis• Main prognostic factor – “topography” 3
– Highest level of extension of the tumor– Upper-segment tumors - poorest prognosis
• Overall prognosis 10
– Poor – Mean survival of around 2 years

• Rare malignant tumor – smooth muscle cells of the media
• Diagnosis challenging– non-specific complaints - dyspnea, malaise,
weight loss, and abdominal or back pain
• Various imaging modalities assist diagnosis– echocardiography, CT, MRI, PET, and PET/CT– make earlier diagnosis possible
• Aggressive surgical management combined with adjuvant therapy
